Efectos funcionales e histológicos posteriores al implante de células madre pluripotentes en un modelo murino con esfinterotomía

Introduction and aimsFecal incontinence is a disabling condition with devastating consequences for the patients. Medical and surgical options are not very satisfactory, reason by which regenerative medicine has been considered in this field. In the present research, we analyzed functional and histologic effects after implanting pluripotent stem cells (PSCs) in a murine model with sphincterotomy.Materials and methodsFemale Wistar rats were subjected to sphincterotomy and divided into three groups. Group 1 (control group) was treated with 300 μL of balanced saline solution and group 2 (late treatment) and group 3 (early treatment) received 50,000 PSCs resuspended in 300 μL of balanced saline solution. All animals were evaluated through high-resolution anorectal manometry 24 hours before and after sphincterotomy and every month for three months. Finally, the rats were euthanized and histopathologic sections from the anal canal were obtained.ResultsAll groups showed a decrease in resting anal pressure and squeeze anal pressure 24 hours after sphincterotomy. At the third month, higher anal pressures in the groups treated with PSCs were detected. Regarding the histologic effects, the microscopic architecture was restored and there was a significant decrease in the inflammatory response in the groups treated with PSCs.ConclusionPSCs implantation improves anal tone, as well as histologic structure, presenting better regenerative results when implanted as early treatment.     

Clinical,radiological and physiological assessment of anorectal function

The maintenance of anorectal continence and defaecation is complex. The disruption of these mechanisms can result in symptoms of either faecal incontinence or obstructive defaecation. Both conditions can have significant impact on quality of life. This article details the clinical assessment of presenting patients to establish potential causes, grade the severity of the symptoms and to assess the impact on their quality of life. The appropriate specialized radiological and physiological investigations aim to evaluate the structural integrity and function of the anal sphincter, the anorectal and pelvic floor musculature and measure the transitory function of the colon.     

肛肠病术后尿潴留穴位干预方法及取穴组方规律研究

目的:研究穴位干预治疗肛肠病术后尿潴留的穴位刺激方法、取穴及组方规律。方法:运用文献计量学的方法对近二十年来穴位干预治疗肛肠病术后尿潴留文献的穴位干预方法、取穴及组方规律进行统计分析。结果:穴位干预方法以灸法为最多,占所纳入文献的51.61%,其次为穴位注射和穴位按摩。关元为取用次数最多的穴位,占56.45%,其次为中极、气海、三阴交、足三里。在运用针法灸法治疗肛肠病术后尿潴留的组方中,双穴配伍时以关元、中极组合出现频率最高,支持度92.94%;三穴配伍时以气海、关元、中极组合出现频率最高,支持度为72.94%。在运用其他穴位刺激方法治疗肛肠病术后尿潴留的组方中,当运用双穴配伍时,支持度最高的也为关元、气海组合,支持度为58.82%;当运用三穴配伍时,中极、气海、关元亦为支持度最高的组合,支持度为35.29%。结论:肛肠病术后尿潴留的穴位干预方法多以灸法等舒适方法为主,取穴多以下腹部任脉穴为主,组方多为3~5个穴位。
